Add support for the Fintek F71805f to LinuxBIOSv3. It hasn't been tested yet
because something's failing to build elsewhere, but the stage1 does build, and
for the moment that's what matters. It's based on working v2 code so it should

sizeof(struct lar_header). Such an archive is invalid because the

be at least 1 byte in the "empty filename" case (only terminating \0).
Improve LAR code documentation and reorder variables in one assignment
to make the code more obvious and readable. This will help people
understand what the code does when they look at it half a year from now.

number from ELF as segment number in the file. This works nicely when
there are no skips (e.g. not PT_LOAD segments, which are discarded).
If one segment is skipped, we get a bump:
normal/payload0/segment0 (27288 bytes, lzma compressed to 14506 bytes @0x64c0)
normal/payload0/segment2 (211136 bytes, lzma compressed to 70905 bytes @0x9dc0)
The LAR loader wont load segment2, and in this particular case, grub2-lb
will only boot into rescue mode (segment0 contains it).
Attached patch adds a counter for segment number in the LAR utility to
solve this bug:
normal/payload0/segment0 (27288 bytes, lzma compressed to 14506 bytes @0x64c0)
normal/payload0/segment1 (211136 bytes, lzma compressed to 70905 bytes @0x9dc0)
Also the eagle eyed can see that I merged in Uwe's multiple-payload
patch into current stage1, which includes the segment support. And this
means that grub2-lb without any hacks works when loaded from LAR segments.

one common file.
The first is the noelf option, which is a simple
modification to look for payloads in the form
payload/segmentX where X is a number.
The segments are assumed to be contiguously numbered and the code
steps when the first search fails (i.e. if 0 and 1 are there, and 2
is not, the code stops and will not try to find 3).
The lar code will use the loadaddress to load the segment. Currently,
the lar code will not run each loaded segment, but we need to consider
this for uwe's lbmenu work. Consider this implementation somewhat
preliminary until we integrate lbmenu. There is the complex issue of
interdependent segments, as in the kernel, where no single segment
can run until all are loaded.
The second is the fix for improperly wrapping to 0 when
searching the LAR.
This has been tested with filo and BOCHS.

The system will default to old behaviour. See Kconfig in the root.
I still wish to kill ELF mode very soon, however.
LAR is a very capable format. With two simple extensions, we can use
LAR to replace all that we are using ELF for now. This change can
really make life better:
1. we can use streaming decompress instead of the current "uncompress
elf to memory and then copy segments" approach. So we can get rid of
THIS hardcode:
#define UNCOMPRESS_AREA (0x400000)
2. A simple lar l can show ALL segments, including payload segments
3. It's really easy to see where things will go in memory, and catch problems
4. We can figure out an ELF input file is bogus BEFORE we flash, not
AFTER we flash and try to boot it
5. did I mention streaming decompress?
6. We no longer have to worry about where we decompress the elf in
memory (this problem was causing trouble when the payload was a linux
kernel -- it was so big)
7. Since we have a load address, we can create this lar entry:
normal/cmdline
and specify that it be loaded at a place where linux will find it as
the cmdline.
8. The decision on whether to XIP can be made in the LAR entry, not in
hardcode. For example, if initram needs to be XIP, set the load
address to 0xffffffff. Done.
The change is simple. Add a load address and entry point to the lar
header. Extend the lar tool to parse the elf file and create multiple
lar segments. It looks like this:
normal/payload0 (33192 bytes, lzma compressed to 18088 bytes @0x38
load @0x100000, entry 0x105258)
normal/payload1 (72 bytes, lzma compressed to 47 bytes @0x4718 load
@0x1225a0, entry 0x105258)
normal/option_table (932 bytes @0x4798 load @0, entry 0)
normal/stage2 (33308 bytes, lzma compressed to 15474 bytes @0x4b78
load @0, entry 0)
normal/initram (4208 bytes @0x8828 load @0, entry 0)
linuxbios.bootblock (16384 bytes @0xfc000 load @0, entry 0)
